How it's calculated: count the days from today to December 31, 2028 (809 days), divide by 7, and round down — 809 ÷ 7 = 115 full weeks. Subtracting the current week number from the year's total also gets close, but drifts in 53-week ISO years, so we count days instead.
In Excel or Google Sheets:=MAX(0, INT((DATE(2028, 12, 31) - TODAY()) / 7))or, rounding to the nearest week instead of down:=MAX(0, ROUND((DATE(2028, 12, 31) - TODAY()) / 7, 0))Both formulas return zero after the year ends.
